Samsung Electronics Co. has begun implementing its next-generation 2.5D chip packaging technology Interposer-Cube4 (I-Cube4).
Samsung’s I-Cube is a heterogeneous integration technology that horizontally places one or more logic dies (CPU, GPU, etc.) and several High Bandwidth Memory (HBM) dies on top of a silicon interposer, making multiple dies operate as a single chip in one package.
Samsung’s new I-Cube4, which incorporates four HBMs and one logic die, was developed in March as the successor of I-Cube2. From high-performance computing (HPC) to AI, 5G, cloud and large data center applications, I-Cube4 is expected to bring another level of fast communication and power efficiency between logic and memory through heterogeneous integration.
“With the explosion of high-performance applications, it is essential to provide a total foundry solution with heterogeneous integration technology to improve the overall performance and power efficiency of chips,” said Moonsoo Kang, senior vice president of Foundry Market Strategy at Samsung Electronics. “With the mass-production experience amassed through I-Cube2 and the commercial breakthroughs of I-Cube4, Samsung will wholly support customers’ product implementations.”
